Researchers from Drexel University in Philadelphia have investigated the effects of dietary protein intake and exercise in reducing the risk of sarcopenia. Their findings were published in the journal Nutrition Research.

In the review, researchers associated aging with sarcopenia, a progressive decline in mass and strength of the skeletal muscle. This can lead to morbidity, reduced quality of life, and even mortality. This is commonly experienced by older adults, with age-related muscle changes adversely affecting muscular strength and their ability to function.

Aside from looking at the relationship between protein intake and regular exercise and reduced sarcopenia risk, they also evaluated which measurement tools could for determining each factor.

The review highlighted the need for further research on the following areas:

Safety and effectiveness of a dietary protein intake of 1.4 grams per kilogram of body weight (g/kg) for older adults.
